Replacing a color filter
The MAC Viper Profile has eight dichroic color filters. See the MAC Viper Profile User Guide available for
download from www.martin.com for names and part numbers.
Use only genuine Martin™ color filters. Handle and store filters with care. Wear cotton gloves while handling
them and keep them perfectly clean.
To replace a color filter:
1. Disconnect the fixture from power and allow it to cool for 30 minutes.
2. Remove the head covers, position the head with the front glass angled downwards and the top side
facing upwards, and apply the tilt lock (see “Access to the head” on page 17).
3. See Figure 22. Remove one of the gobos from the left-hand gobo wheel A as described in “Replacing
rotating gobos” on page 22 (making sure that you line up the magnet with a reference point), so that you
have access to both sides of the color wheel B.
4. Turn the color wheel B until the filter that you want to replace C is accessible. Put on clean cotton gloves
and hold the filter near its outer edge between finger and thumb. Pull the outer edge of the filter away
from the color wheel slightly to release it, then lift the filter carefully out of its clip and remove it. Store the
filter resting on a clean, soft surface or in a filter rack.
5. To insert a color filter, put on cotton gloves and turn the
filter so that its coated side will face towards the lamp.
To find out which side of the filter is coated, hold an
object up against the glass. There will be a gap
between the object and its reflection on the non-coated
side.
6. Slide the filter into its clip in the center of the color
wheel. See Figure 23. Make sure that the outer edge of
the filter locates under the lip (arrowed) on the edge of
the color wheel so that the filter is held securely.
7. If necessary, continue replacing filters one by one as
described above.
8. When you have finished replacing color filters, replace
the goboholder that you removed as described in
“Replacing rotating gobos” on page 22.
9. If no further service work is to be carried out, reinstall
the head covers as described in “Access to the head” on page 17 and release the tilt lock before
reapplying power.
